ok here is what i did to fix it might help some of ya

1. Edit the mas_ratings.php file like Ntfu2 said
in the modcp/mas_rateapp.php file line 29 looks like

FROM mas_application

To This

FROM vb_mas_application

2. GoTo phpmyadmin and then selcet your db that vbulletin is in, then click the SQl tab, then in the input box enter this below then click Go

RENAME TABLE mas_application TO vb_mas_application,
             mas_rating TO vb_mas_rating;

3. go set your vBulletion Options for this hack, then test the application by going to /modapp.php and see if it works, working for me!!!

of course changing the all the vb_ to YOUR boards table prefix!!!
